1. Hardware decoding was only ever introduced recently into 1.7 which
complicates things.  One of which is that in order to know a frame has been
decoded, we listen to a callback which currently passes through the main thread
and if that thread is blocked, stalls occur, removing the position slider,
removes that bottleneck.
2. GStreamer 1.5 (into 1.6) was over a year long effort and many changes were
made to various elements/libraries so it's very imprecise as to what state your
1.5 application is in.

Another interesting point, there are constant caps queries occurring throughout
the entire failing video taking a significant amount of time that doesn't seem
to occur with the the re-encoded videos.
